BitArray.Count
Syntax
Int32 Count
Description
The BitArray.Count property contains the number of elements in the bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
MyLabel.Text = "Number of members: "+b.Count.ToString();
BitArray.IsReadOnly
Syntax
Boolean IsReadOnly
Description
The BitArray.IsReadOnly contains a Boolean value that is used to determine the read-only status of the bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
MyLabel.Text = "Is BitArray read-only?: " + b.IsReadOnly.ToString();
BitArray.IsSynchronized
Syntax
Boolean IsSynchronized
Description
The BitArray.IsSynchronized property contains a Boolean value that is used to determine whether the bitarray is synchronized.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
MyLabel.Text = "Is BitArray synchronized?: " + b.IsSynchronized.ToString();
BitArray.Item[]
Syntax
Boolean BitArray.Item[ Int32 index]
Description
The BitArray.Item[] property is used to access individual elements of a bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
MyLabel.Text = "Second element is " + b[1].ToString();
BitArray.Length
Syntax
Int32 Length
Description
The BitArray.Length property can be used to both access and change the length of the bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
ba.Length = 40;
MyLabel.Text = "Length of array: " + b.Length.ToString();
BitArray.And()
Syntax
BitArray And( BitArray value )
Description
The BitArray.And() method is used to perform the 'And' logical operation on a bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray b2 = new BitArray(3);
BitArray results = new BitArray(3);
results = b.And(b2);
BitArray.Clone()
Syntax
Object Clone()
Description
The BitArray.Clone() method returns an object containing the bitarray on which this operation is being performed.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray results = new BitArray(3);
results = (BitArray)b.Clone();
BitArray.CopyTo()
Syntax
Void CopyTo( Array array, Int32 index )
Description
The BitArray.CopyTo() method copies a bitarray to an array passed in as the first argument, starting at an index provided by the second method argument.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
Boolean[] MyArray = new Boolean[3];
b.CopyTo(MyArray, 0);
BitArray.Get()
Syntax
Boolean Get( Int32 index )
Description
The BitArray.Get() method returns the value of a specific element of a bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
Boolean MyBool;
MyBool = b.Get(0);
MyLabel.Text = "MyBool is " + MyBool.ToString();
BitArray.Not()
Syntax
BitArray Not()
Description
The BitArray.Not() method performs the Not logical operation on a bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray results = new BitArray(3);
results = b.Not();
MyList.DataSource = results;
MyList.DataBind();
BitArray.Or()
Syntax
BitArray Or( BitArray value )
Description
The BitArray.Or() method uses the value argument to perform the Or logical operation on a bitarray.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray b2 = new BitArray(3);
b.Or(b2);
BitArray.Set()
Syntax
Void Set( Int32 index, Boolean value )
Description
The BitArray.Set() method sets an element of the bitarray that is given by the first argument to the value provided in the second argument.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray.SetAll()
Syntax
Void SetAll( Boolean value )
Description
The BitArray.SetAll() method sets all elements of the bitarray to a value provided as the argument to the method.
Example
BitArray b = new BitArray(3);
b.SetAll(true);
BitArray.Xor()
Syntax
BitArray Xor( BitArray value )
Description
The BitArray.Xor() method performs the Xor logical operation on a bitarray, using the value that the bitarray passed in as the argument to the method.
Example
BitArray b = new BitArray(3);
b.Set(0, true);
b.Set(1, true);
b.Set(2, false);
BitArray b2 = new BitArray(3);
b.Xor(b2); |
